    This work investigates the process of mosaicking overlapping video frames of individual tree stems in sub-canopy scenes captured with a portable multisensor instrument. The robust commercial computer vision systems that are in use today typically rely on precisely controlled conditions. Inconsistent lighting as well as image distortion caused by varying interior and exterior orientation parameters can complicate image mosaicking in a sub-canopy environment. This paper presents how the image, range, and orientation data are used to guide the mosaicking algorithm used in the Tree Measurement System (TMS). The mosaicked images will be an important step in data reduction leading to the continued development of a portable tree-stem sampling instrument.
